Abstract:
Swath sonar bathymetry data used for that dataset was recorded during RV Heincke during cruise He525 using the onboard Kongsberg EM 710 multibeam echosounder. The cruise took place between 2019-03-05 and 2019-03-08 in the German North Sea. Data were recorded on 3 days between 2019-03-05 and 2019-03-07. The approximate average depth of the entire dataset is around 20 m.
To enhance MBES data accuracy, one sound velocity profile casts were conducted in the vicinity of the working area prior to the survey using sound velocity profiler MIDAS SVP 3000. After processing, these data were directly imported into the MBES Acquisition software Kongsberg SIS Seafloor Information System. Raw data were converted to MB-System format. Data were automaticallay and manually edited for false measurements. No further artificial sound velocity profiles were used during further processing. The data were corrected for tidal changes using data provided by the OSU Tidal Prediction Software OTPS that is retrievable through MB-System. The vertical datum of the data is now matched to mean sea level (MSL). Raster were calculated and stored in as GRD-files (Float-32, netCDF, EPSG 4326).
